It is similar in power to the GTX 760, which was a bit too pricey for us on this occasion. And, yes, that is a cut above the GTX 750 we've used in our build. The PS4 has a Radeon-based graphics processor that's said to be roughly comparable with the Radeon R9 270x. As our Steam Machine is intended to work primarily with 1080p TVs rather than super high-end 4K monitors, we're pretty happy with that. It's one of the new NVIDIA Maxwell generation GPUs, designed to bring pretty good gaming performance across the board at 1080p resolution, with low power use and low heat output.

The 1GB version is available for as little as £80, it's not particularly power-hungry and offers good performance for the price. However, after having a chat with NVIDIA, whose graphics cards are currently afforded the best support by SteamOS, we decided on the GeForce GTX 750. With a relatively low budget, we couldn't really afford a super-high-end graphics card. Minimum spec - NVIDIA graphics card (AMD and Intel support incoming)
